Abstract: A method for cleaning the interior of a pipe using a cleaning device which has a tube. The tube is set into an axial movement along a main axis H within the pipe, and the insertion depth E of the tube into the pipe is detected. It is determined whether the tube has reached an end position, and the axial movement is terminated when the tube reaches the end position.

Abstract: A method for cleaning the interior of pipes using a cleaning device and a cleaning device. The cleaning device has a tube and an advancing unit for moving the tube along a main axis (H) of the advancing unit. The advancing unit has a drive which is frictionally connected to the tube and by which the tube is moved in an axial direction along the main axis (H). The advancing unit is set into a rotational movement about the main axis (H) during the axial movement of the tube, and the drive transmits the rotational movement to the tube.

Abstract: A fault detector for detecting the occurrence of a rapid pressure rise within electrical equipment. The fault detector has a chamber having an interior, a diaphragm in sealing engagement with the chamber and an aperture providing fluid communication between the interior of the chamber and the external environment of the chamber.

Abstract: A system and method for generating measurable social impact, the system and method comprising tracking a transaction, wherein the transaction comprises a purchase of at least one good or service, wherein the at least one good or service is associated with a social impact partner, and wherein the transaction is captured in a first blockchain record on a first blockchain, collecting a purchase amount of the transaction, sending, to a second computing device, at least a portion of the purchase amount of the transaction, wherein the second computing device is associated with the social impact partner, and tracking, at the server, a receipt of the at least a portion of the purchase amount of the transaction at the second computing device, wherein the receipt is captured in a second blockchain record on the first blockchain.

Abstract: A method and to a cleaning device for cleaning tubes of tube bundles, wherein at least one rotating cleaning lance is used. During the insertion of the cleaning lance, the insertion depth E of the cleaning lance is measured and is stored and documented in a storage and documentation device. The cleaning device has an XY displacement device, on which a support rail is arranged, which supports a cleaning apparatus.
